Hi Guys
I am working on a project that requires a battery backup to keep the pic running, to run a clock.
The PIC runs on 5v, my power supply supplies both 12v and 9v, the 9v feed is supplied to a regulator to supply 5v to my pic.
The 12v feed from the PSU supplies various devices.
The idea is that when the main power shuts down the 12v feed will cut off, stopping all external devices, the 9v feed will be backed up by a 9v PP3 rechargeable battery.
Just wanted to ask if a PP3 battery is acceptable in such an application, i have seen various onboard backup batteries but they are all 3.6v.
Is there a way to make a 3.6v battery work for this application??
